Indeed. It's getting harder and harder to find what you want lately. There were always occasions where books wouldn't show up in searches but it seems to be much worse now. If someone posts a listing called "Dog Pot Yoghurt", I expect that to come up if I search for "Dog Pot Yoghurt" in 'All Categories', whether they posted it in the Yoghurt category or Fish Fingers category. An exact wording title match should always appear regardless. And surely, they'd get more sales if it did?
Dog Pot Yoghurt - great series! Although I favour the Sanskrit variants.
As I said, it's refinement for the sake of it. Whether the move is counter-intuitive is beside the point, as it's all about "progress".
